Abstract

In this article, I show how the principle of democratic self-determination can answer the boundary problem by both grounding and constraining a people’s right to exclude potential immigrants. I argue that a people has the qualified right to exclude insofar as it respects the self-determination claims of outsiders. I analyze the concrete implications of the requirement to respect the self-determination claims of outsiders in the cases of long-term residents, refugees, and brain drain. Sometimes the only way for a people to respect the self-determination claims of outsiders will be by including, rather than excluding, them as members.
